The essentials
Tow-starting If the engine will not start, first try starting it
us
in
g the battery of another vehicle
››› page 69. You should only attempt to tow-
start a vehicle if charging the battery does
not work. This is done by leveraging wheel
movement.
When tow-starting a vehicle with a petrol en-
gine, do not tow it more than a short dis-
tance, otherwise unburned fuel can enter the
catalytic converter.
● Engage 2nd or 3rd gear before moving off.
● Press the clutch and hold the pedal down.
● Switch the ignition on.
● Once both vehicles are moving, release the
clut c
h.
● As soon as the engine has started, press
the clutc
h and move the gear lever to neutral.
How to jump start Jump lea
dsThe jump lead must have a sufficient wire
c
r
o
ss section.
If the engine fails to start because of a dis-
charged battery, the battery can be connec-
ted to the battery of another vehicle to start
the engine. Jump leads must comply with standard
DIN
72553 (see cabl
e manufacturer's instruc-
tions). The wire cross section must be at least
25 mm 2
for petrol engines and at least
35 mm 2
for diesel engines. Note
● The v ehic
les must not touch each other,
otherwise electricity could flow as soon as
the positive terminals are connected.
● The discharged battery must be properly
connected t
o the on-board network. How to jump start: description

prox. 10 km/h (6 mph). If the vehicle is pass- ing at a considerably higher speed, no indi-
cation wi
ll be displayed.
The faster the vehicle approaches, the sooner
an indication will be displayed in the external
mirror, because the blind spot detector takes
into account the speed differential with other
vehicles. Thus even though the distance from
the other vehicle is identical, the indication
will appear sooner in some cases and later in
others. Physical limitations inherent to the system
In some situation
s the blind spot detector
may not interpret the traffic situation correct-
ly. E.g. in the following situations:
● on tight bends;
● in the case of lanes with different widths;
● at the top of slopes;
● in adverse weather conditions;

PinMeaning
12Unassigned
13Earth for pin 9 Trailer power socket
The v
ehic
le is fitted with a 13-pole power
socket for the electrical connection between
the trailer and the vehicle. With the engine
running, electrical devices on the trailer re-
ceive power from the electrical connection
(pin 9 and pin 10 of the trailer power socket).
If the system detects that a trailer has been
connected electrically, the electrical equip-
ment on the trailer will receive voltage
through this connection (pins 9 and 10). Pin
9 has a permanent live. This powers, for ex-
ample, the trailer's interior lighting. Electrical
devices such as a fridge in a caravan only re-
ceive electrical power if the engine is running
(through pin 10).
To avoid overloading the electrical system,
you cannot connect the ground wires of pin
3, pin 11 or pin 13.
If the trailer has a 7-contact connector , you
will need to use an adapter cable. In this case
the function corresponding to pin 10 will not
be available. Tow rope
The to
w r
ope must always be securely fixed
to the towing vehicle and loose enough so
that the vehicle can handle turns smoothly.
However, make sure that the cable does not
rub on the ground while driving.
Trailer rear lights
Always check the trailer's rear lights to en-
sure they are working correctly and that they
comply with the relevant safety regulations.
Make sure that the maximum permissible
power that can be absorbed by the trailer is
not exceeded ››› page 276.
Connection to the anti-theft system
The trailer is included in the anti-theft system
if the following conditions are met: ● If the vehicle is factory-equipped with an
anti-theft al
arm and towing bracket.
● If the trailer is electrically connected to the
tow
ing vehicle through the trailer power
socket.
● If the electrical systems of the vehicle and
trail
er are in perfect condition and have no
faults or damage.
● If the vehicle is locked with the key and the
anti-theft al
arm is activated.
When the vehicle is locked, the alarm is trig-
gered if the electrical connection with the
trailer is cut off.
